The parties signed a letter of agreement at a ceremony held in Singapore on January 20. The joint research project, called "Green Corridor," aims to reduce merchant vessels' emissions of NOX and SOX in advance of international treaties calling for stricter emissions standards, and will examine the technological and economic feasibility of an LNG-fueled bulker.
“As we approach the entry into force date for sulphur emissions, we are seeing interest in LNG as a ship fuel start to climb again,” says Morten Lovstad, DNV GL – Maritime Business Director Bulk Carriers. “As one of the largest LNG exporters in the world and with bunkering infrastructure coming online, Australia is well placed to support the bulk trade on the west coast with LNG as fuel. By working together with some of the industry’s technology leaders we are confident this new project has the potential to deliver a competitive, compliant and safe vessel and the business case to back it up.”
Woodside COO Mike Utsler said Woodside was excited to be a part of this joint industry project to be led by DNV GL: “We recognise that LNG as a transport fuel option presents opportunities, both in a commercial sense and as a low-emissions alternative to other marine fuels. This JIP importantly is bringing together mining companies, a shipowner and supplier, a ship designer and LNG producer and led by DNV GL to explore how we can develop the LNG fuelled 'Green Corridor'. Woodside is this year taking delivery of the first LNG fuelled marine support vessel in the Southern Hemisphere and we look forward to the findings from this joint industry project on the potential for LNG fuel use by bulk carriers,” he said.
The JIP has two main objectives – building and assessing the business case of LNG as fuel for Capesize bulkers operating in the trade between Australia-China, and developing an efficient LNG fuelled Capesize concept design. These activities will be run together, with the immediate results generated from one project fed into the other.
The financial and technical feasibility study examines a LNG fuelled Capesize bulker operating from Australia. It will look at a wide range of factors including the capital costs, operational costs and price sensitivities in terms of LNG and low sulphur marine fuel oils, in comparison to both a conventionally fuelled vessel and a LNG retrofit, as well as undertaking a high level bunker supply chain assessment to identify the key issues affecting the vessel design and business case.
The project partners will also work to develop a concept design for an efficient LNG fuelled Capesize vessel. The ship will be optimized for operations from and to Australia, and will be developed to a technical stage so that it may achieve an Approval in Principle (AiP) in compliance with the new DNV GL rules. An Approval in Principle is an independent assessment of a concept within an agreed framework, confirming that the design is feasible and no significant obstacles exist to prevent the concept from being realized.
SOX emissions from vessels are addressed in the International Convention for the Prevention of Pollution from Ships (MARPOL) Treaty Annex VI (prevention of air pollution), and vessels are required to use bunker fuel with a sulfur content of 0.1% or less in Emission Control Areas (ECAs) such as North America. In general sea areas (all excluding ECAs), the treaty is expected to reduce the maximum sulfur content of bunker in use from the current standard 3.5% to 0.5% in 2020. The regulation will be applied to vessels already in service.
